Un organoétain est un composé chimique qui possède au moins une liaison étain(Sn)-carbone(C). Dans tous les organoétains produits industriellement, l'atome d’étain est tétravalent [...] Les organoétains sont donc micro-, di-, tri-ou tétrasubstitués par des groupements d’origine organique [...]. Du fait de la présence des substituants hydrocarbonés, les organétains sont hydrophobes. Leur solubilité dans l'eau est donc faible. Elle dépend du pH, de la salinité et de la température du milieu. 5, record 2, French, - organo%C3%A9tain

Tout tritium n’ est en fait pas nécessairement produit de fission. En effet, l'origine de cet isotope radioactif de masse 3 de l'hydrogène est multiple. On le trouve dans l'environnement, parce qu'il est produit naturellement par l'action des rayons cosmiques sur les atomes d’oxygène et d’azote, mais aussi du fait des retombées des tirs nucléaires. Il est produit dans le combustible irradié à raison d’1 atome pour 104 fissions d’uranium dans les réacteurs à eau ordinaire par exemple, par fission ternaire [...] 5, record 3, French, - tritium

Effet Auger : processus d’auto-ionisation d’un atome, au cours duquel un électron excité communique à un autre électron d’une couche externe une énergie suffisante pour l'extraire de l'atome sans émission de proton(processus «non-radioactif»).
